Shuttle operator to bid for commercial flights

CAPE CANAVERAL, Fla. - NASA contractor United Space Alliance is preparing a long-shot bid to continue flying the shuttle as a commercial service after the space agency completes its last three planned missions this year.

Starting as soon as 2013, after construction of a new external tank, the lead operator of NASA's shuttle fleet proposes to fly twice a year with Atlantis and Endeavour at a cost of under $1.5 billion a year.

If supported, the plan would reduce an anticipated gap of at least four years between launch of the last shuttle mission this year and availability of new privately run crew taxis, a period during which astronauts will depend on Russian spacecraft to reach the International Space Station.

"We thought this was a good option to be put on the table to be evaluated with all the other commercial options, since it's a vehicle that has really proven itself," said Mark Nappi, head of Houston-based USA's Florida operations. "It is safe. We have a lot of history, we understand how to operate it."

Nappi has told the company's employees the proposal is "very much a long-shot."

USA has proposed a six-month study of the commercial-shuttle option.

The company asked NASA to help fund the study under a program set up to speed the development of new rockets and spacecraft able to carry people. Winners of the program's $200 million second round of funding are expected to be announced next month.

NASA has refused to comment on any of the companies' bids.

Nappi said it was too soon to estimate how many local jobs USA's Commercial Shuttle Transportation Service could produce. The company's local workforce is expected to drop from 3,900 now down to about 1,000 after the last mission.

The nearly $1.5 billion program proposed by USA is less than half the $3.1 billion budgeted for the shuttle in 2010. For about the same amount, NASA has contracted with SpaceX to fly 12 cargo flights to the station with its much smaller Dragon spacecraft, and SpaceX said it expects four crewed flights a year to cost $560 million.

With tight budgets anticipated for years, continued spending on the shuttle would divert money from development of new commercial crew taxis and other projects.

Some have called for the shuttle to be retired for safety reasons.

But one space expert said USA's idea merits consideration as a way to ensure that NASA's top priority, the space station, continues to run smoothly.

"You need to have backup options, and this is a potentially expensive but very capable backup option that should be considered," said Scott Pace, director of the Space Policy Institute at George Washington University.
